Mac OS Personal Web Sharing
is software you can use to create your own Web server and
share files with everyone on the Internet. Once you set up
your server, add content to it, and turn on Web Sharing,
others who know the address of your server can visit your
personal site and view its content. As long as your computer
is connected to a TCP/IP network (intranet or Internet) and
your server is running, the server's content is available to
all users of the network, regardless of the browser or the
kind of computer they're using.
